The founders excluded the children of foreign nationals with the natural born citizen clause.
By definition those born with multiple nationalities are NOT NATURALLY Americans.
The example of the Kenyanesian Usurpation should be a clear enough example that they were right to anyone.
Yet we still have people even here on FR arguing that children born to one American parent in a foreign country are eligible to be President.
Anwar Al-Awlaki’s kids born in Yemen are just as eligible to be President as Ted Cruz.
